The pay-for-configuration is an interesting development, allowing non-geeky users to use one of the most undervalued Windows Live services. Yes Custom Domains works with Windows Live Mail Desktop, and Messenger and everything else from Windows Live. So if you haven’t got an @live.com address yet, perhaps now is the time to be creative?

PS: There is a neat Custom Domains manager from Frameworkx.com. Expect an updated version to take advantage of the new features soon!
